The good news.... this massive SCCA , Televised event, will be held in Monterey this year.
The bad news..... I dont have a car that fits any class..... but one, and not very well.
BUT, I think im going to run it anyway.

SCCA made a regional class for the X speedGT WC cars and it was called "STO". now, they have stuck it into the national class, GT2 which is basically the Panos and GT3 cup cars (stock like run in the supercup series). what that means, is those are 1:31 cars at laguna seca. (and my top times are in the 1:36s) BUT, there is a sub class for the STO type cars called GT2-ST........ and thats where the 928 might fall, because it has a VTS due to anderson and me running in the WCGT races.
So, it will be like a world challenge GT race of back in 2005, but how much fun will that be to put the car on TV again. maybe i can find some ways to get the power up to get in the top 10 (i.e. Andersons CF intake might do the trick)

Now, i have to get that transmission fixed as well. anyone know where i can get a used or new 5th gear set???

Calling Greg Brown. ready to do some work on the Holbert transmission which looks only to need 5th gear set and a couple of synchros?

Anderson! I think you need to enter your cup car in this race!! certainly would be a top 10 car!!!

Mark,

The SCCA made the announcement about 90+ days ago regarding the next three years. In addition
to Laguna in 14', they'll go to Daytona in 15' and Mid-Ohio in 2016. We're all hoping that Indy is chosen
for 2017, especially since they're holding vintage races there for 2014.

Some serious tune time, plus you need to get the $$ to Greg now so he can have your intake ready by spring.

The "Only needs fifth gear and a few synchros" is the simplified description of "disassembly of everything between the input shaft and the pinion gear, plus the input shaft and the pinion gear", right? Replace all the worn and damaged bits. Reassemble. Fifth-gear bits are more rare than "scarce", last I heard.

Adding more power and running skinny street tires will extend the life of the new gearbox parts, as will relacement 6mm CV-joint to drive flange bolts in grade-3. Get a case of those bolts....

Just signed up for some open track time on 1/25 at WSIR, the Zombie is almost ready to roll again. Awaiting my new fatass seat, fresh belts and my HANS.

How much power would Anderson be allowed to have in the Zombie for this GT2-ST class at Laguna?

We can make that happen between now and then.

mark kibort

thats why Im asking. where are the 5th gear sets?? any out there at all?
maybe another transmission all together? as far as what it takes. sure, its a transmission rebuild... its not rocket science, but i would like it to be done right.
Id pay a little more to have GB do it vs the usual suspects. (CT automotive)

tune time? dont know how much i would need, considering the little anderson had on the stock ECU and intake combo. 520rwhp is not bad. since i dont have the valves and port work, i would be very happy at 440rwhp for laguna in my car. certainly would put the car in the mix.

the form andersons car was in, would be what it could run based on the VTS. If you win, you might have problems defending a lot of the car though.

What is going on at WSIR on the 25th?

Rob Edwards

Last time I asked about a 5th gear for a G28/13 or G28.55, they were available but were $1607. That was June 2012. Am afraid to ask what they'd be now.

BC, 1/25-26 is POC's first PDS track weekend of the year. There's some open track time so I can get a feel for the Zombie.

James Bailey

Willow is open track day plus driving schools for HPD and possibly race license for those who have the required background....

.."Only needs fifth gear and a few synchros" ... Now that is pretty funny

mark kibort

Thats what most transmission failures need. . However, i dont think i need shift forks, or other gears. sure its a total rebuild, but what do you think the cost will be?

on my current transmission, i wore out something on the gear or synchro in 2nd for which keeps it in gear during an unloaded condition. is that the synchro that is worn, or the gear itself. that might be the cheaper box to modify, but i want to keep it in the car and racing until the holbert transmission is fixed. then, fix the current box and sell it off to offset the cost of the holbert trannie.

BTW, both have nice LSDs in them, so at least , i know thats worth something in the end.

dr bob

Mark,

Snchronizers don't hold the gears engaged, they just help the sections match speeds when you shift. If it's coming out of gear on a trailing throttle, you'll want to shop for the gears, sleeves and maybe the shift fork. Plus every bearing you find in there will be grumbly from the metal bits circulating around. Jim B can give you an idea how easily a "just needs one of these parts" project can quickly escalate to a major parts replacement effort. There's no method that I'm aware of to 'un-wear' the worn parts, so after you get a look at the car-nage you have to decide if you are feeling lucky and are willing to nurse the car around with a weakened box that doesn't shift well, or go for the right fix. Labor's pretty much the same the first time, again the second and the third times too.

Call Mark and Roger to see about the gear sets and other parts. They have access to Porsche's wordldwide parts inventory listings.

Rob Edwards

Was just at 928Intl, 928 302 905 32 is NLA new, anywhere, from Porsche.

If your having Doc rebuild your trans be sure to have him install a spray bar cooler system like the GTS run, but use an electric pump like a tilton......add a temp gauge too....Anderson used to peg 300F before he added a cooler!!!

I think Anderson just rebuilt his cup car......

mark kibort

I dont know what keeps the gear engaged, and its not at trailing throttle. trailing throttle and full or part throttle is find. its when you are in the no force point. (no accel or decel) , that it comes out of gear. no part or metal in oil to speak of. this might be a normal rebuild with a need for 2nd gear if that is what is the cause of the "poping out". remember this current S4 box also has the problem of locking in a gear, where the only way to fix it was to pull the cover and unlock it. it works, but it has to be shifted very selectively, rather than bang bang shifting. this might be shift forks or something else.

this is why im leaning toward the S4 box, which had a quick strip of the 5th gear set and then it was coasted in to the pits. all the other gears look fine visually, but yes, your right , you never know. Ive had a few boxes rebuilt over the years and it can be a pandora's box of requirements. synchros, forks, sliders, etc. If i can find the 5th gear, i would like to get the Holbert box rebuilt, or if its too far gone, then maybe combine parts of the two gear boxes to make on gear box that works. (aside from any parts that makes sence to be replaced with new)

now, the first thing is to see if i can find a 5th gear somewhere.

anyone anyone??

mark kibort

Thanks for checking! Un real that this part is so scarce! oh well. guess Ill have to find it in a junk yard or buy an entire parts car.

Whats the gear teeth count on the 5th gear set. 32/23 comes to mind. are there some 5th gears that wont work? or better said, are there others that will work?

James Bailey

those are the layshaft ratios which effect all the gear ratios but 5 th gear....they do vary somewhat but as you have argued for years it matters little, just changes shift points...

Your best option, least expensive probably is combine your two transmissions and HOPE you get enough good bits to make one box...then sell the extra limited slip.
